He stirs the oblation of fat with the rib; the rib is the middle of cattle, the fat is the sap of cattle; in that he stirs the oblation of fat with the rib, he places sap in the middle of cattle. Now they kill [1] the beast when they dispose of it; the expiration has Indra for its deity, the inspiration has Indra also. 'May Indra's expiration be set in every limb', he says; verily he bestows expiration and inspiration upon cattle. 'O god Tvastr, let much be united for thee', he says; for cattle have Tvastr as their deity. 'When ye that are various become of one form', he says; for they being various become then of one form. 'Over thee as thou goest among the gods [2] for help let thy comrades and thy father and mother rejoice', he says; verily he makes him, approved by his mother and his father, go to the world of heaven. With a half-verse be offers the oblation of fat; the half-verse is yonder (sky) and the half-verse is this (earth); verily with sap he adorns both. He offers to the quarters; verily with sap he adorns the quarters; verily from the quarters he wins strength and sap. The speckled butter is the expiration and the inspiration of cattle; cattle have the lord of the forest [3] for their deity; in that having made offering of the speckled butter he says, 'Recite for the lord of the forest, give directions for the lord of the forest', he bestows expiration and inspiration upon cattle. Of each he divides the divided pieces; there fore cattle have various forms. He moistens (it) with soup; soup is the sap of cattle; verily he bestows sap upon cattle. He invokes the Ida; the Ida is cattle; verily he invokes cattle. Four times he invokes [4], for cattle have four feet. If he desire of a man, 'May he have no cattle', he should take for him (a piece) without fat; cattle are distinguished by fat; verily by means of their distinctive mark he deprives him of cattle, and he has no cattle.
